This is the replacement to the extremely popular, fan-favorite, EV-Peak Q6400AC. This unit adds a great new look as well as some extra features such as LiHV compatibility.

This is the EV-Peak 400Watt Four Port Quad Charger. The charger has a selectable voltage switch so it can be used worldwide.

LiHV Battery Support
This high-end charger supports the new LiHV chemistry battery! Charge, discharge and storage charge your LiHV’s

Charge FOUR batteries at once! Even if they are not the same chemistry, voltage, or capacity. This charger has 4 individual charge ports and plugs directly into the wall. It also can be connected to a DC power source such as a 12V car battery or a DC Power Supply. The Charger also features Lithium Battery Balance Charge, Storage, and Discharge modes.

High Power:
The CQ3 can output up to 100Watts/10Amps from each port at the same time! Each port is fully independent of each other and has its own dedicated power! Using 100Watts/10Amps on a port in no way limits any of the other ports’ ability to charge to its full potential! Max the charger out by using 100Watts/10Amps on each port at the same time for a total of 400Watts!

EV-Peak is known for their great reliability. They use the best internal components and circuitry available to create long lasting products. Their reliability rivals that of name brand manufacturers such as Hitec, Duratrax, Traxxas, etc. And all this is backed by an easy 1 year warranty!

High Power Output:
This charger boasts 100Watts of power per port! Most chargers such as Hitec only offer 50Watts per channel. But this charger leaves them all in the dust, allowing your packs to charge faster! It offers a 10Amp charge rate!

Digital Power Mode
Each Port can act as a power supply! Use this function to power external items such as a pit light, tire truer, motor checker, charger, or anything else that runs off of DC power. Both the Voltage and Amperage are adjustable to suit the needs of the connected device.

Lithium Cell Check
Check the voltage of a Lithium battery’s cells when plugged into the balance port. Simply hold the INC button when in a Lithium menu. The screen will provide a readout of each cell’s voltage.

Adjustable Cutoff Voltage
The voltage per cell at which the charger stops charging the battery can be adjusted for fine user precision. Adjustments available for LiPo, LiHV, LiIo, LiFe, Pb batteries.

    Great seller! Thank you.

  8. dopa-bob-i7epohg6j

    Definetly worth the money. Simple to set up, easy to use, does everything it advertised, takes the mystery out of charging lipo batteries.

  9. Gary Davis

    Will charge my nimh batteries just fine but will not charge my lipo batteries. Contact toy giving me connection break message. The batteries I’m trying to charge are brand new

    • dirtcheaprc

      We contacted the customer to work this out. Thank you.

  10. Jon Dimitz

    Great charger / worked well for months. In a hurry and connected the 12-volt clips backwards to the car battery. This destroyed the charger in a matter of seconds / went up in smoke quickly! Pay attention to the connections to the car battery.

  11. garrett newman

    Great charger. If you are charging xt60 lipos then you need to order 4 charging leads with xt60’s or be ready to make your own from the provided t-connectors. I wish it would charge in 50 mah increments so i could fully charge my 1550’s but other than that its nice.

  12. kalani938

    Very very impressed with this quad charger. People complain about the loud fan, but it doesn’t seem too loud to me. Plus it keeps it very cool. Definitely recommend! Very good power vs other quad chargers in its price range.

  13. priusmedic

    Well built excellent charger. If you have ever used a 4 button charger then you will be right at home with this one. It has plenty of power for charging multiple big batteries fast and does not heat up like my previous chargers when working them hard.

    I only have a couple of small complaints that really do not impact the chargers functionality.

    1. The fans continue to run after a program has completed.
    2. When saving an individual battery program the safety parameters are not stored (capacity, timer, etc…) You have to manually input them when changing battery types.

    Other than those minor complaints this unit rocks!

  14. ajdebock-4

    Just what I needed. Love all the features it has! Great charger!

  15. 333gas333

    Fast shipping! Item as discribed.

  16. rmossesq

  17. Fishdog

    Great charger. Charges all my batteries real fast

  18. lowerghut2

    DirtCheaps a great seller!!! Smooth Transaction!!!! Always Recommended!!!!

  19. rmossesq

    This is a quality unit. Not a cheap charger at all. It is made of metal, the displays are bright, the switches have a quality feel. It is larger than I expected (It is four chargers in one – duh! Of course it’s big!). It also isn’t completely automatic. You have to set it when you charge a battery but it is super easy to use. If you make a wrong choice setting up a battery, a warning goes off. Nice feature. There also are no battery clips for DC use. That was a little disappointment. There is a lead but no clips. Regardless, if you have some larger sized lipos that you need to charge, I highly recommend this unit. Even the box it comes in makes a nice storage box for it while sitting in the shop.

  20. monkeypics

    Thanks for the charger guys!

  21. dnj-enterprise99

    Quick to ship, great communication, would buy again from them anytime!!!

  22. Jeffrey Lawes

    This product is pricey but worth it. It saves me a lot of time to be able to charge and balance four batteries at the same time. The 100 watts per channel is awesome. Many chargers out there will only have 50 watts per channel. I definitely recommend this product and buy it from Dirt Cheap RC. It is an awesome store.

  23. 0027hawk

    Fast shipping great transaction great price great product seller is top notch A+
